The resulting compounds of the Formula I may be converted into pharmaceutically active compounds for example by converting the 3- methylene group to a 3-oxo group followed by conversion to the corresponding 3-methoxy-3- cephem compound or a derivative thereof or by converting the 3-methylene compound I to the corresponding 3-methyl-3-cephem compound. Intermediates of the Formula III may be formed by salt formation from the free acid, forming the 1-oxide from the 1-unsubstituted compound, acylating an amino group in the 7- position or forming a lactone across the 3,4 ring position by hydrolysis of a 3-acetyloxymethyl group to hydroxymethyl and effecting cyclization with the free acid group at the 4- position. Pharmaceutical compositions of the above mentioned pharmaceutically active compounds with the usual excipients show antibiotic activity when administered euterally or parenterally.

Patent GB-2005750-A (GB)
Title: Drilling stabilizer including mechanical interlock device
IPC: F16D1/091
Filed: 1978-09-01
Abstract: A rigid stabilizer sleeve 56 is slidably received over a drill collar 54. A pair of internal clamping rings 83, 74 are slidably received through each end of the rigid main sleeve. As a threaded end cap 12 is threaded into the rigid main sleeve, the end clamp forces one ring of the pair against the other thereby producing a clamping effect whereby the stabilizer can be clamped at any desired position on the drill collar 54. The ring 83 of the pair has a groove 84 and a rib 82 disposed on its interior cylindrical surface, which groove and rib interlock with a rib and a groove disposed upon the outer cylindrical surface of the end cap 12, whereby when the end cap is threadedly removed from the rigid main sleeve, the ring 83 follows the end cap and is disengaged from the inner ring 74, thereby unclamping the pair of rings from the drill collar. <IMAGE>

Title: Measuring thickness capacitively
IPC: B29C48/92
Filed: 1979-10-01
Abstract: A capacitance sensor 10 comprises a slotted conductive body 11 with an electrode 29 symmetrically disposed in the slot 13 and insulated from the body 11.

Title: Ventilating apparatus for sealed spaces
IPC: F24F8/108
Filed: 1980-03-04
Abstract: Ventilating apparatus for sealed spaces comprises an air lock, the interior of which is at least partly lined with sound damping material (13), the air lock having an opening in which there is arranged a motor driven air fan (2) and also having a screened air discharge aperture.

Patent GB-2071961-A (GB)
Title: Electro-acoustic transducer
IPC: H04R11/06
Filed: 1980-03-11
Abstract: Electro-acoustic transducers of the rocking armature type are well-known, and have been adopted by the British Post Office for use on the ear-pieces of telephone subscribers' instruments. In such a transducer, the armature is centrally pivotted, and when driven by the speech coil it rocks about the central pivot. One end of the armature is coupled by a drive pin to the apex of a basically diaphragm. The movement imparted to the apex of the diaphragm by the armature end includes a lateral component, which can produce undesirable frequency irregularities in the characteristics of the device. This is overcome, by the inclusion of a thin washer (15) of a resilient plastics material between the front face of the rim of the diaphragm and the transducer case. This washer, which in one case is of polyethylene 0.002" thick, damps out these irregularities. This enables a simple conical diaphragm to be used, which is cheaper then the flared diaphragm hitherto used. In addition, it reduces the number of transducers rejected due to unsatisfactory frequency characteristics. <IMAGE>

Patent GB-2049556-A (GB)
Title: Single cycle printing machine
IPC: B41K3/64
Filed: 1980-04-29
Abstract: A single cycle printing machine comprises a rotary printing drive mechanism (3), (33), a detent (23) for locking the mechanism, release means (37) for disengaging the detent (23), thereby to free the drive mechanism and actuating means for operating the release means. The actuating means is mechanical and comprises sensing elements (41, 43) for sensing the presence or absence of a sheet to be printed. In the event of a sheet not being correctly located a weaker spring (69) allows sensing element (43) to lower when a rotary shaft (73) is driven thereby inhibiting actuation of the release means (37), whilst if a sheet is correctly located the sensing element (41) is made to descend by stronger spring (63) to cause actuation of the release means (37) which removes detent (23) from driven pulley (3) to initiate a printing cycle. The invention avoids the use of micro-switches for sensing the correct sheet position and enables simpler drive mechanism to be employed. <IMAGE>

Title: Improvements in or Relating to Stabilising Bluff Structures against Oscillation
IPC: E02B17/00
Filed: 1980-10-10
Abstract: Method and apparatus for stabilising an upright structure such as a pile (1) against transverse oscillation due to the relative horizontal motion of the sea past it. Gas is discharged from orifices formed either in a ring duct (3) surrounding the pile, or (16) in the wall of the pile itself. The bubbles tend to rise within the region (18) of low pressure which forms closely downstream of the pile, so breaking the synchronism of the known vortex-shedding mechanism that can promote the transverse oscillation. A perforated shroud (13) may surround the structure and the bubbles may rise within the gap (14) between structure and shroud. Such a shroud may itself have some stabilising property even when the gas supply is turned off. <IMAGE>
